It's to know the model number of the chip used for your TFT module that you should do first.
Raspberry Pi https://github.com/nopnop2002/lcd_id
It's the same outward appearance, but mcufriend has a lot of variations. http://domoticx.com/arduino-shield-2-4-tft-lcd-touch/
And Sailor's information makes a mistake in most cases.
i had this output Read Registers on MCUFRIEND UNO shield controllers either read as single 16-bit e.g. the ID is at readReg(0) or as a sequence of 8-bit values in special locations (first is dummy)

but then i tried sketch from another issue and the output is

This is real pfd5408.

Your LCD is the one I don't know.
Read Registers on MCUFRIEND UNO shield controllers either read as single 16-bit e.g. the ID is at readReg(0) or as a sequence of 8-bit values in special locations (first is dummy)

Your TFT may be ILI9340.
reg(0x00D3) 00 00 93 40 ILI9341, ILI9488
But it's not support.
Hi. can you help me with your lib, i run your examples, but it doesnt work, only white screen, i checked pins, all connected right
